Because there is a STRIP_NOPS in fold_binary and then we look at
BIT_NOT_EXPR's operand which is a NOP_EXPR. Maybe we should fold
~(int)unsigned_var into (int)~unsigned_var and that would fix the
issue all the time.
As an aside note, I see we might have a type issue with BIT_NOT_EXPR:
else if (TREE_CODE (arg0) == BIT_NOT_EXPR)
return TREE_OPERAND (arg0, 0);
if we have ~(int)~unsigned_int, we will get the incorrect type returned.
Thanks,
